On my S5360 I would like to replace the default Pico TTS engine with Svox Classic with the Victoria voice - sounds much more human. I have downloaded and installed the engine and the free offer of Victoria for two weeks. However, when I go to Settings to set Svox Classic as the default, I find only Pico as an available engine. I tried starting the app in case it needs some further set-up, but it says 'Svox Classic is not selected as your default TTS engine - go to TTS settings'. So I am stymied, and the two week trial is being used up. Would it work if I bought the Victoria voice? - it's only £1.99 or something like that! How can I get the Svox engine recognised as one of those available? Many thanks for any help.
